Mounting crawfish

A crawfish or "land cra " will serve as a typical medium for describing the method of preparing specimens of this nature.

When possible, take notes of the living colors.

Crustaceans may be killed most handily with chloroform. Place the specimen in a large mouthed bottle or other vessel that may be
closed tightly. Pour a little chloroform upon a wad of cotton and drop it into the vessel with the specimen and close up tightly.

When beginning work, lay the specimen upon its back and with a sharp scalpel loosen the large thorax plate around its edge and remove it carefully with head and antennae left attached intact.

Separate tail entire from body meat. Split it along fleshy under side and remove muscles from it with the scalpel.

The legs will come apart and must be kept in natural order. If the claws are large and meaty, cut a round hole in under side of thick
part and scrape meat out. Apply arsenic-water to all inner surfaces.

Cut wires of suitable size for all the legs. Have them enough longer than the legs so that a sharpened end will protrude to run
through and clinch in the body core. Push wires in full length of legs. (Fig- 30. shows the details of making the body core of fine
excelsior.)

Make the core of a size to fit a little loosely into shell of body and tail.

Set legs upon core as shown in Fig. 31.

When the legs are properly anchored, cover the core with enough of compo. No. I, so it will fit snugly into thorax and tail shells. Place these upon the core now and press them accurately into position.

Whatever compo. squeezes out may be removed with a bit of damp cloth or sponge. Position legs and tail approximately and wire upon the base. Set the legs in their permanent position, spread or close the tail fan as desired, arrange the antennae, and set the specimen in a well ventilated spot to dry. Tint with oil colors, thinned with kerosene as they are used, laying the tints on with soft brushes.

Sanded or graveled board bases may be made for birds, turtles, etc., by applying a coat of heavy shellac to top and sides of pieces, cut
to required sizes and shapes, and before the shellac has a chance to dry, throwing sand or fine gravel on forcibly or laying the boards in the sand and piling sand over the moist tops, letting them lay a few moments before removing and shaking off the loose sand. Allow
such bases to dry thoroughly before using.
